BODY-FAT TIGHTENING

Before stars take it all off for the camera, they disrobe for their dermatologist. "We'll essentially redo the entire surface of their body," says Jaliman, who starts with radio frequency, namely Thermage, to tighten loose skin right away. Also in demand is CoolSculpting, a fat-freezing device that obliterates belly bulges, love handles, and back fat. "Six weeks after treatment, patients begin to pee out the metabolized fat," says Jaliman. "They're so svelte, they can retire their Spanx."
